Soudal Stay Fresh Acetoxy

Product Information

The Soudal Stay Fresh Acetoxy is an acetic curing sanitary silicone sealant designed for sealing applications in environments with high humidity levels. It is a low modulus acetoxy silicone that cures quickly to form a flexible, 100% silicone seal without shrinkage. The product is ice white in colour and supplied in loose packaging.

This sealant contains anti-fungicidal agents that inhibit mould growth, making it appropriate for sealing sanitary ware such as baths, basins, showers, and toilets, as well as glazed tile surrounds. It exhibits primerless adhesion to common sanitary materials including ceramic tiles, porcelain, metals, and wood. The sealant is resistant to ultraviolet light, rain, snow, ozone, and various chemicals, and maintains performance across a wide temperature range.

Fitment & What to Check

Check compatibility with the substrate material to confirm primerless adhesion applies. Confirm that the joint dimensions fall within recommended sealant width and depth guidelines for acetoxy silicones. Ensure that curing conditions allow for acetic acid release without affecting sensitive surrounding materials.

Common Ordering Mistakes

• Ordering a different silicone type (e.g., neutral cure) when acetoxy cure is required for specific adhesion or chemical resistance
• Selecting incorrect packaging size or form for the intended application method
• Overlooking colour matching for visible sealant joints in sanitary installations
